HEAT-REGLATOR FOR INCUBATORS.

E Specification of Letters Patent.

Application filed June 21, 1913.

To all whom t may concern:

Be it known that I, CHARLES P. HEIM- BoUiiGER, a citizen of the United States, residing at Beardstown, in the county of Cass and State of Illinois, have invented a new and useful Heat-Regulator for Incubators;`

This invention relates regulators for incubators, and particularly to an intermittently operated circuit closer,

uniform temperature.

One of the features of theinvention is the rating armature and the adjustable block (which is mounted upon the insulating base) are in circuit, and when the heat rises above substantially 103 degrees, which is the necessary temperature, he mercury in a thermometer will form a Contact with alead connected tothe magii thereby energizing the magnet which will attract the free end of the vibrating armature, opening the circuit at of the vibrating armature, thereby extinguishing the light of the electric lamp or bulb. Th ii as the temperature decreases, the mercury of the thermometer will descend and break the contact with said lead restoring the lamp to the magnet, thereby circuit.

In the drawings the lamp is disposed immediately below an opening, which is covered by a bell-shaped closure, which is raised and lowered by electrically operated means, which together with the bell closure auxiliary means for regulating the heat or temperature in as shown in the I- desired,

and j set forth, shown be of any suitable heat chamber is an the free endthe incubator.v drawings, vthe Patented Mar. 9, i915@ smal No. 775,127.

bell closure may be adapted to open and close an opening, directly under which a coal oil lamp may be arranged.

In practical fields the minor details of O construction may necessitate alterations, to

which the patentee is entitled, provided the lalterations fall within claimedl The invention comprises further features combinations of parts, as hereinafter in the drawings and the scope of what is claimed.

In the drawings: Figure 1 is a View showing the improved main and auxiliary heat regulators as applied to an incubator. 2 is a plan View of the main regulator showing its circuits, showing parts of the circuit closing apparatus in section. Figf is a side View of the circuit ig. 4 is a view showing the auxiliary regulator as applied to a incubator.

Referring more particularly to the drawings, 1 designates an incubator, which may shape and construction, and arranged on the interior thereof in the electric lamp or bulb 2 (in lieu of which a rheostat, not shown, may be substituted). Also arranged on the in# terior of the incubator in the 'heat chamber 3 is a thermometer et, the lower end of which is provided with a contact 5 to which a lead 6 is connected. This contact forms an electric connection with the mercury 7 of the thermometer. The lead 8 extends through the upper end of the tube of the thernioni` eter and provides a contact 9, with which the' mercury intermittently contacts as'the same rises and falls, incident to- .magnet 12 is electrically connected'to the extend into' the core 14, thereby not only instable, the vibrating armature easily adjusted vin its proper relative posi-- holding the core in position, but also hold ing thespool in position. The'base 15 is "provided with a guide groove19,'in"which a copper member or block 2() is arranged. This member or block'20 is provided' witha slot 21, through which a thumb screw 22 vextends and is threaded into the base; It will be seen that' owing to the slot 21, the Yblock or member may be adjusted, while the thumb screw 22 holds the block in adjusted positions. By making the block ad- 23 may b e tion to the' p bles of themagnet, so'that the armature will properly contact with the pole pieces 'of the magnet., Adapted to`be .attractedVY by. the soft iron lmembers -or ll Jrackets-,1l3 and 16a. (which constitute the poles of the magnet) is a'- vibrating armature 23, the free end of which is provided `with a contact 24, and when the free'endeof said vibrating armature 23 is down, the contact 24 contacts with the end of thethumb 'screw-25, which is threaded into a-stud 26 mounted upon i the base.v Connecting, the

studs 26v` and the binding post 27 of the battery 34 is provided, .the positive lead or Y .over the lead or wire 38.- As the heat from f Y the contact 9 of the lead` or the wire 8, cur-r of the magnet' thereby energizing the saine,- which in turn will cause the soft iron brackets'or poles 16 'wire35 which, including'the switch 36, is

connected at-37 to the lead or wire 6, while thenegative vwire 38 'of the battery iscon- Inected to a binding post 39 of the block 'or member 20. y -When the switch 36 is closed, current passesalong the lead' 35.to the electriclamp 'or-bulb, tothe stud 26 by-way of the lead 28 being.

through the vibrating armature, the same member or vblock 20, and back to the'battery the electric lamp or bulb rises over 1.03 degrees the mercury willmake contact with rent passing through the coils and 16a to attract the vibrating armature 23, the free end of which will break contact with the screw 25; thereby opening the elec-'- tric lamp or bulb circuit, extinguishing the light from which the heat emanates, and asl tions, adevice -and 'battery in said circuit,

the heat decreases,.the mercury also cooling off and lowering, the circuit is bro'kenat the contact 9, which will cause the magnet to be vcome denergized, thereby permitting the electric lamp or bulbcircuit to become refes'tablished. The making `andbrealring of in contact with the screw 25, to the'- these circuitsoccur intermittently, as then-lf temperature rises and ialls in the heat chamgfv ber ofthe incubator.

rnrig. 1vl a Win be Seen that the decise f lamp orbulb is located immediately below anopening 40 of, the' incubator, which is .normally kept closed by the bell closure,

which is pivotally suspended from a rod 42 adgustably connected at 43 to the oscillatory beam 44, which is pivoted at 45170 a bracket 46. A baseof insulating material 47 is pro-' vided, upon which a magnet 48 similar to the magnet 12 is mounted. A core-49 -is threaded yinto tlieb'ore 50 of `the magnet, while a screw l'is threaded through the base 47 and into the core 4.t9- The oscillatory beam 44.- isgfpivotally connected at 53 to they gplunger, which extends into the bore of the magnet.V A suitable battery 55 is provided, the positive lead 56 of which extends through the upper end of a second thermom' eter 57 and forms a contact 58, while the negative lead or wire 59 of the battery cen- -nects at 60 to the windings ofthe magnet. A contact 61, with Awhich the mercury of the thermometer cooperates electrically is connected to the windings of the magnet at 62, by means of a wirevor lead 63.- The. bell closure 41 is normally held closed owing to the spring 65, whichfconnectsthe ma et and the oscillatory bar' orfb'eani` proved electrical means, constitutes auxil-` iary means for keeping the' temperature inl .i oscillating the bar 44, w-hichwwill raise the bell closure. This construction obell closure and the :means for `operating thesame will morequickly allow theescapeof the heat in; the incubator, which4 will cause the -mercury'of the thermometer ll'to more quickly le'ool oil' and descend, than if the heat was just allowed to gradually decrease in temperature. f

As shown'in Fig. 4 the bell closure may be used in connection with a coal oil lamp heated incubator.
